I have it too, but I didn't even notice it at first, or even consider it worth commenting on if it hadn't been brought up here first. I don't consider it an issue at all, do you?

(assuming it is IBIS .. and leaving video out of the equation):

it causes an unnecessary drain on the battery

it causes the camera to overheat under hot temperatures (and hence, having negative impacts on the SNR of the sensor.. or worse, forcing the camera to shutdown)

Both are likely .. since it was one one of the main reasons (particularly my 2nd point) why IBIS was only switched on during the shot itself .. and not clear (yet) how Olympus worked around that issue.
